  template: `
    ...

    <button (click)="repeat.emit()">Repeat</button>
  `
})
export class SomeComponent {
  readonly repeat = createRepeat();

  // Will log 'hello' directly, then each time the 'Repeat' button gets clicked
  readonly #sayHello = rxEffect(of('hello').pipe(this.repeat()), console.log);
}
